MAJOR FEATURES + CHANGES
==========================

Change 3358140 on 2017/03/22 by Rolando.Caloca

	DR - Fix copy to cube face
	- Compile fix when using dump layer
	- Add new error enum

Change 3358301 on 2017/03/22 by Mitchell.Wilson

	Initial check in of LODs in InfiltratorForward. First pass on optimization in level. Adding a visibility track for SceneCapture2D in tunnel section.

Change 3358477 on 2017/03/22 by Mitchell.Wilson

	Updating Skeletal Mesh DPW_Robot_Export to resolve screen size being too low for LOD1. Cleaned up LOD1 which was showing some visible popping when transitioning.

Change 3358529 on 2017/03/22 by Mark.Satterthwaite

	Globally disable clang's "constant-logical-operand" warning when running under Distcc - it is much easier and less invasive than constantly fixing the code.

Change 3358745 on 2017/03/22 by Mark.Satterthwaite

	Disable another warning (parentheses-equality) under Distcc because again the separation of preprocessing from compilation means it turns up where it isn't expected.

	* Planar reflections are now supported in splitscreen

Change 3360758 on 2017/03/23 by Daniel.Wright

	[Copy] Added new light property bCastVolumetricShadow, which defaults to true for directional and sky lights, but false for point / spot lights as supporting volumetric fog shadowing has significant GPU overhead

Change 3360762 on 2017/03/23 by Daniel.Wright

	[Copy] Texture flags are now properly routed to RHICreateTexture3D from the render target pool

	[Copy] Distance field cvar comments

Change 3360782 on 2017/03/23 by Daniel.Wright

	[Copy] Disabled selection color on Volume materials

Change 3360795 on 2017/03/23 by Daniel.Wright

	[Copy] Volume materials now specify Albedo and Extinction, which is more intuitive than Scattering and Absorption.  Albedo is [0-1] reflectance, while Extinction is a world space density.

Change 3360799 on 2017/03/23 by Daniel.Wright

	[Copy] Cinematic scalability levels get 2x volumetric fog resolution in x and y

Change 3360806 on 2017/03/23 by Daniel.Wright

	[Copy] Fixed volumetric fog being offset when viewport min is not 0

Change 3360809 on 2017/03/23 by Daniel.Wright

	[Copy] Volumetric fog now adds a bias to the inverse squared light falloff denominator, prevents extreme aliasing from the hotspot.  Can be controlled with r.VolumetricFog.InverseSquaredLightDistanceBiasScale.

	Volumetric fog supports static shadowing from Stationary lights
	* Using bilinear on static shadowmap depths + 1 PCF to smooth out results

Change 3366029 on 2017/03/27 by Daniel.Wright

	Static shadow depth maps for Stationary point and spot lights are 2x higher res by default (4x more texels), which is more appropriate for volumetric fog

	Missed a file.

Change 3367838 on 2017/03/28 by Richard.Wallis

	Updated items from original shelved version by Mark Satt:

	- Added MetalBackend.cpp to change main function string to have an initial crc + code length zero's

	**Description below taken from Mark Satt's original verison of this in CL3343280**

	Updated for Dev-Rendering's PSOs & integrates Richard's work on RHI shader libraries.

	Replace the FShaderCache's cook-time binary shader cache with Dmitriy Dyomin's standalone FShaderCodeLibrary that saves all shader byte-code arrays to files named by the FSHAHash. This de-duplicates shaders so we only ever store the byte code once. Includes optional support for generating a platform specific library file - which Metal implements to provide a single Metal library. The platform-native implementation can perform more de-duplication and in the case of Metal has lower file overheads and will compress more efficiently.

	- All of the support code for the FShaderCache's cook caching is gone, which affects all platforms. The FShaderCodeLibrary is currently  supported by Cook-By-The-Book but can be used with iterate or child cookers - only DLC cooking requires further work.
	- With further modifications it should be possible to support Cook-on-the-Fly as well (output directories would be needed in FShaderCodeLibrary::InitForCooking) and the file-access pattern should be changed to use async. IO so that Material loading is not considered complete until all required byte-code arrays are loaded into the FShaderCodeLibrary.
	- For Metal archiving shaders this way will compile with debug information and the FShaderCodeLibrary, with some help from extensions to IShaderFormat, will save the debug information out into separate files during cooking - these can then be used to debug the game without having to locally recompile, recook & repackage but the shipped byte-code is stripped. Global shader caches are also subject to de-duplication in the library in order to support Metal's shader stripping.
	- File Move operations need to respect the 'Replace' flag - for FShaderCodeLibrary to work we need Move to be atomic.
	- This bumps the object version and will cause all content to recook.
	- Native library support is optional - only Metal currently implements one, but so could Vulkan and D3D12. For Metal the big advantages are further de-duplication where different materials generate the same MetalSL text but a different FSHAHash, that the single Metal library has lower overhead and that as a single file it all compresses far better (esp. with LZMA - 5x smaller).

Change 3367854 on 2017/03/28 by Mark.Satterthwaite

	Don't track or record draw call resources for non-OpenGL shader platforms in the shader-cache as it is unnecessary and makes it slower on the CPU than it needs to be.

Change 3367877 on 2017/03/28 by Brian.Karis

	Fixed linux build hopefully

Change 3368001 on 2017/03/28 by Mark.Satterthwaite

Change 3368019 on 2017/03/28 by Mark.Satterthwaite

	And another fix for Windows compilation of MetalShaderFormat.

Change 3368042 on 2017/03/28 by Mark.Satterthwaite

	Remove temp working directories after archive packages built.

Change 3371641 on 2017/03/30 by Rolando.Caloca

	DR - Copy 3371640 (fix mem leak)

Change 3372436 on 2017/03/30 by Uriel.Doyon

	Added flags in UPrimitiveComponent to keep track of its state in the streaming manager.
	This allows to avoid unnecessary callback and processing in begin destroy reattach and being destroy logic.

	Removed the limitation of only processing UMeshComponent when handling spawed primitive.
	This releases the level manager from having to manage dynamic primitives.
	This improves performance by not having to manage dynamic references in the level manager.

	Primitives managed as dynamic now have a callback when ever their proxy is udpated, handling
	many cases automatically where previously a manual callback to notify would have been required.

	Fixed an issue where primitives with no reference to streaming textures would loose they dynamic state
	because of lack of references in the streamer.

Change 3372740 on 2017/03/30 by Chris.Bunner

	[Experimental] Partial compute post process pipeline (r.PostProcess.PreferCompute).
	StencilSceneTexture added to deferred list.
	A few known issues to be fixed in a follow-up CL.

Change 3372765 on 2017/03/30 by Uriel.Doyon

	LPV Fade support
	- mostly integrated from CL 2959511

Change 3373272 on 2017/03/30 by Uriel.Doyon

	Refactored common param code to shared sub-class in CombineLUTs and Tonemap PS/CS.
	Skip compute post process out-of-bounds writes.
	Unsigned type conversion fixes.
	Trimmed compute post process shader inputs.

Change 3374233 on 2017/03/31 by Chris.Bunner

	Removed several redundant post process compute fences and resource transitions.
	Added testing CVar to force compute post processes to async (r.PostProcess.ForceAsyncDispatch).

Change 3374412 on 2017/03/31 by Rolando.Caloca

	DR - Fix static analysis

Change 3374544 on 2017/03/31 by Richard.Wallis

	FShaderCache Parallel-Context-Aware Merged with FShaderCache Single Library.

	Future Work
	- This was done before Engine PSO were in so this now needs a refector in the recording and playback on pipeline states instead an emulate PSO in OpenGL Driver.
	- Remove FShaderCacheState and replace the logic with FGraphicsPipelineStateInitializer which should be able to record from the RHI current pipeline state
	- This would reduce the Locking required as it's naturally per thread/context and only the final record would need a lock

	Copying Metal improvements from task stream, with some modifications:
	- Off-by-default implementations for MTLFence & MTLHeap, including some small changes to the RHI interface for parallel contexts.
	- Support for Apple's Instruments "Points of Interest" tool.
	- Consolidation of some Mac & iOS compiler, memory and thread handling code.
	- Fixes for Metal not having implicit buffer SRV typecasting for DistanceField effects.
	- Improvements to the internal FMetalDebug layer, still off by default.
	- Limited support for Xcode automatic code-signing for iOS/tvOS.
	- Minimisation of render-target changes in some rendering code, esp. SceneOcclusion, DBufferDecals.
	- Added RHISetResourceAliasability_RenderThread to FDynamicRHI for RHIs to implement simple render-target aliasing.
	- Added FApplePlatformObject, a custom block allocator for Objective-C types (with NSZombie support) which is now used in MetalRHI to decrease allocation costs of Objective-C types.
	- Smattering of lesser fixes.

Change 3375654 on 2017/03/31 by Mark.Satterthwaite

Change 3376756 on 2017/04/03 by Guillaume.Abadie

	Fixes scene captures ordering's backward compatibility.

	Before, 2d scene captures were rendered before cube scene captures. The CaptureSortPriority broke backward compatibility by settings this new member to 0 in the USceneCaptureComponent's constructor. Since it is a higher come first policy, this CL set the default of this value to 1 in USceneCaptureComponent2D's constructor.

	Partial code tidy up.

Change 3310187 on 2017/02/17 by Chris.Bunner

	Preserve constant expressions rather than always casting after translating a material attribute. Losing the notion of constant means we can't correctly detect used properties and falsely enable e.g. PDO. Happened because of the incorrect component masks in BreakMaterialNodes which then had to be downcast to the correct type which is done as an inline fragment rather than swizzle expression.

	#jira UE-41594

Change 3310215 on 2017/02/17 by Chris.Bunner

	[Copy] Added 'r.AOListMeshDistanceFields' which dumps out mesh distance fields sorted by memory size, useful for directing content optimizations

Change 3333705 on 2017/03/06 by Daniel.Wright

	[Copy] Mesh distance fields are now 8 bit fixed point by default, but can be changed back to 16 bit floating piont with a project setting.
	* 8 bit uses half memory but introduces error for thin surfaces or large meshes.

Change 3333721 on 2017/03/06 by David.Hill

	DecalProxy:
	Copy float FadeScreenSize to FDeferredDecalProxy for use in the render thread.  This avoids  pointer chasing to the UDecalComponent (game thread component).

Change 3333772 on 2017/03/06 by Daniel.Wright

	[Copy] Scene motion blur data is only updated for the main renderer frames.  Fixes scene captures and planar reflections breaking object motion blur.

Change 3333790 on 2017/03/06 by Daniel.Wright

	Non-editor compile fix

Change 3333836 on 2017/03/06 by Daniel.Wright

	[Copy] Workaround for gobal distance field volume textures being bloated by 4x on PS4 due to the recommended tiling modes.  They now use a 2d tiling mode which avoids the bloat, saving 96Mb.

Change 3333869 on 2017/03/06 by Daniel.Wright

	[Copy] Volumetric Fog using a volume texture mapped to the camera frustum
	* Volumetric fog can be enabled on an Exponential Height Fog component with additional controls
	* Lights have a VolumetricScatteringIntensity
	* New cvars r.VolumetricFog, r.VolumetricFog.GridPixelSize, r.VolumetricFog.GridSizeZ, r.VolumetricFog.DepthDistributionScale
	* Lighting features supported:
	   * Directional light with CSM and a light function
	   * Point / spot lights without shadows / light functions / IES profiles
	   * Skylight with occlusion from distance fields
	* Analytical height fog covers the view range past where the volumetric fog ends
	* Temporal reprojection is used on the volumetric fog scattering and extinction to achieve stability
	* Translucency integrates properly into volumetric fog
	* Height fog StartDistance is not supported by volumetric fog and should be set to 0.

Change 3333894 on 2017/03/06 by Daniel.Wright

	[Copy] Initialize GDummyVolumetricFogGlobalDataUniformBuffer outside of parallel rendering

Change 3333902 on 2017/03/06 by Daniel.Wright

	[Copy] Fixed volumetric fog trying to render light functions for a point light

Change 3333908 on 2017/03/06 by Daniel.Wright

	[Copy] Volumetric materials
	* Added new material domain Volume, which can output Scattering, Absorption and Emissive.  All properties are in world space densities.
	* Particle systems using the Volume domain are voxelized based on their ParticlePosition and ParticleRadius
	* Volumetric fog integration is now energy conservative - scattering is integrated against transmission over the depth of each slice.
	* Added bOverrideLightColorsWithFogInscatteringColors to exponential height fog, which can be enabled to make Volumetric Fog match Height fog more closely

Change 3334134 on 2017/03/06 by Daniel.Wright

	[Copy from Michael Trepka] Added Embree 2.14.0 and changed MeshUtilities to use it as this solves issues with Embree leaking TLS keys. UnrealLightmass is still using older Embree 2.7.0 until we can find time to properly test it with the new version. Also, invalidated distance field DDC to force it to rebuild with updated Embree.

==========================
MAJOR FEATURES + CHANGES
==========================

Change 3219796 on 2016/12/02 by Rolando.Caloca

	DR - vk - Increase timeout to 60ms

Change 3219884 on 2016/12/02 by Daniel.Wright

	Assert to help track down rare crash locking capsule indirect shadow vertex buffer

Change 3219885 on 2016/12/02 by Daniel.Wright

	Fixed saving a package that doesn't exist on disk but exists in p4 at a newer revision when the user chooses 'Mark Writable'

Change 3219886 on 2016/12/02 by Daniel.Wright

	Don't create projected shadows when r.ShadowQuality is 0
	* Fixes crash in the forward path trying to render shadows
	* In the deferred path, the shadowmap was still being rendered and only the projection skipped, now all cost will be skipped

Change 3219887 on 2016/12/02 by Daniel.Wright

	Changed ClearRenderTarget2D default alpha to 1, which is necessary for correct compositing

Change 3219893 on 2016/12/02 by Daniel.Wright

	AMD AGS library with approved TPS
	Disabled DFAO on AMD pre-GCN PC video cards to workaround a driver bug which won't be fixed (Radeon 6xxx and below)

Change 3219913 on 2016/12/02 by Daniel.Wright

	Level unload of a lighting scenario propagates the lighting scenario change - fixes crash when precomputed lighting volume data gets unloaded

Change 3220029 on 2016/12/02 by Daniel.Wright

	Async shader compiling now recreates scene proxies which are affected by the material which was compiled.  This fixes crashes which were occuring as proxies cache various material properties, but applying compiled materials would not update these cached properties (bRequiresAdjacencyInformation).
	* A new ensure has been added in FMeshElementCollector::AddMesh and FBatchingSPDI::DrawMesh to catch attempts to render with a material not reported in GetUsedMaterials
	* Fixed UParticleSystemComponent::GetUsedMaterials and UMaterialBillboardComponent::GetUsedMaterials
	* FMaterialUpdateContext should be changed to use the same pattern, but that hasn't been done yet

Change 3220108 on 2016/12/02 by Daniel.Wright

	Fixed shadowmap channel assignment for stationary lights which are not in a lighting scenario level, when a lighting scenario level is present

Change 3220504 on 2016/12/03 by Mark.Satterthwaite

	Metal Desktop Tessellation support from Unicorn.
	- Apple: Metal tessellation support added to MetalShaderFormat, MetalRHI and incl. changes to engine runtime/shaders for Desktop renderer and enabled in ElementalDemo by default (OS X 10.11 will run SM4).
	- Epic: Support for different Metal shader standards on Mac, iOS & tvOS which required moving some RHI functions around as this is a project setting and not a compile-time constant.
	- Epic: Fragment shader UAV support, which is also tied to newer Metal shader standard like Tessellation.
	- Epic: Significant refactor of MetalRHI's internals to clearly separate state-caching from render-pass management and command-encoding.
	- Epic: Internal MetalRHI validation code is now cleanly separated out into custom implementations of the Metal @protocol's and is on by default.
	- Epic: Various fixes to Layered Rendering for Metal.
	- Omits Mobile Tessellation support which needs further revision.

Change 3220881 on 2016/12/04 by Mark.Satterthwaite

	Compiles fixes for iOS & static analysis fixes from Windows.

Change 3221180 on 2016/12/05 by Guillaume.Abadie

	More NVAPI warning fixups.

Change 3221219 on 2016/12/05 by Chris.Bunner

	When comparing overriden properties used to force instance recompilation we need to check against the base material, not assume the immediate parent.
	#jira UE-37792

	DR - Lambdaize
	- Added quicker method to check if system textures are initialized

Change 3222290 on 2016/12/05 by Mark.Satterthwaite

	Moved HLOD persistent data to viewstate to fix per-view compatability.
	#jira UE-37539

Change 3223349 on 2016/12/06 by Chris.Bunner

	Fixed HLOD with FreezeRendering command.
	#jira UE-29839

Change 3223371 on 2016/12/06 by Michael.Trepka

	Removed obsolete check() in FMetalSurface constructor

Change 3223450 on 2016/12/06 by Chris.Bunner

	Added explicit ScRGB output device selection rather than Nvidia-only hardcoded checks. Allows easier support for Mac and other devices moving forward.

Change 3223638 on 2016/12/06 by Michael.Trepka

	Restored part of the check() in FMetalSurface constructor removed in CL 3223371

Change 3223642 on 2016/12/06 by Mark.Satterthwaite

	Experimental Metal EDR/HDR output support for Mac (iOS/tvOS need custom formats & shaders so they are not supported yet).
	- Only available on macOS Sierra (10.12) for Macs with HDR displays (e.g. Retina iMacs).
	- Enable with -metaledr command-line argument as it is off-by-default.
	- Sets up the CAMetalLayer & the back-buffer for RGBA_FP16 output on Mac using DCI-P3 as the color gamut and ACES 1000 nit ScRGB output encoding.

Change 3223830 on 2016/12/06 by Rolando.Caloca

	DR - vk - Better error when finding an invalid Vulkan driver
	#jira UE-37495

Change 3223869 on 2016/12/06 by Rolando.Caloca

	DR - vk - Reuse fences

Change 3223906 on 2016/12/06 by Guillaume.Abadie

	Fix alpha through TempAA artifact causing a small darker edge layouts.

Change 3224199 on 2016/12/06 by Mark.Satterthwaite

	Fix a dumb copy-paste error from the HDR changes to Metal.

Change 3224220 on 2016/12/06 by Mark.Satterthwaite

	Fix various errors with Metal UAV & Render-Pass Restart support so that we can use the Pixel Shader culling for DistanceField effects.
	- Unfortunately Metal requires that a texture be bound to start a render-pass, so reuse the dummy depth-stencil surface from the problematic editor preview tile rendering.

Change 3224236 on 2016/12/06 by Mark.Satterthwaite

	IWYU CIS compile fix for iOS.

Change 3224366 on 2016/12/06 by Mark.Satterthwaite

	Simplify some of the changes from CL# 3224220 so that we don't perform unnecessary clears.
	- If the RenderPass is broken to issue compute or blit operations then treat the cached RenderTargetsInfo as invalid, unless the RenderPass is restarted.
	- This guarantees that we don't erroneously ignore calls to SetRenderTargets if the calling code issues a dispatch between two RenderPasses that use the same RenderTargetsInfo.

Change 3224416 on 2016/12/06 by Uriel.Doyon

	New default implementation for UPrimitiveComponent::GetStreamingTextureInfo using a conservative heuristic where the textures are stretched across the bounds.
	Optimized UPrimitiveComponent::GetStreamingTextureInfoWithNULLRemoval by not handling registered components with no proxy (essentially hidden game / collision primitives).

	Added blueprint support for texture streaming built data through FStaticMeshComponentInstanceData.

	Fix for material texture streaming data not being available on some cooked builds.

	Enabled split requests on all texture load requests (first loading everything visible and then loaded everything not visible).
	This is controlled by "r.Streaming.MinMipForSplitRequest" which defines the minimum mip for which to allow splitting.
	Forced residency are now loaded in two steps (visible, then forced), improving reactiveness.

	Updated "stat streaming" to include "UnkownRefMips" which represent texture with no known component referencing them,
	and also "LastRenderTimeMips" which related to timed primitives.
	Changed "Forced Mips" so that it only shows mips that are loaded become of forced residency.

	"Texture Streaming Build" now updates the map check after execution.

	Removed Orphaned texture logic as this has  become irrelevant with the latest retention priority logic.

	Updated "r.streaming.usenewmetrics" so that it shows behavior before and after 4.12 improvements.

Change 3224532 on 2016/12/07 by Uriel.Doyon

	Integrated CL 3223965 :

	Building texture streaming data for materials does not wait for pending shaders to finish compilation anymore.
	Added more options to allow the user to cancel this build also.

Change 3224714 on 2016/12/07 by Ben.Woodhouse

	Cherry pick CL 3223972 from //fortnite/main:

	Disable Geometry shader onchip on XB1. This saves 4ms for a single shadow casting point light @ 512x512 (4.8ms to 1.8ms)

Change 3224715 on 2016/12/07 by Ben.Woodhouse

	New version of d3dx12.h from Microsoft which incorporates my suggested static analysis fixes. This avoids us diverging from the official version

Change 3224975 on 2016/12/07 by Rolando.Caloca

	DR - vk - Dump improvements

Change 3225012 on 2016/12/07 by Rolando.Caloca

	DR - Show warning if trying to use num samples != (1,2,4,8,16)

Change 3225126 on 2016/12/07 by Chris.Bunner

	Added 'force 128-bit rendering pipeline' to high-res screenshot tool.
	#jira UE-39345

Change 3225449 on 2016/12/07 by Chris.Bunner

	Updated engine rendering defaults to better match current best practices.
	#jira UE-38081

Change 3225485 on 2016/12/07 by Chris.Bunner

	Moved QuantizeSceneBufferSize to RenderCore and added call for PostProcess settings. Fixes screenpercentage out-of-bounds reads in some cases.
	#jira UE-19394

Change 3225486 on 2016/12/07 by Chris.Bunner

	Only disable TAA during HighResScreenshots if we don't have a reasonable frame-delay enabled.

Change 3225505 on 2016/12/07 by Daniel.Wright

	Fixed exponential height fog disappearing with no skybox

Change 3225655 on 2016/12/07 by Benjamin.Hyder

	Dirty owning packages when user manually forces regeneration of all reflection captures.
	#jira UE-38759

	DR - Fix recompute tangents disabling skin cache
	- Make some macros into lambdas
	#jira UE-39143

Change 3226212 on 2016/12/07 by Daniel.Wright

	Features which require a full prepass use DDM_AllOpaque instead of DDM_AllOccluders, which can be skipped if the component has bUseAsOccluder=false

Change 3226213 on 2016/12/07 by Daniel.Wright

	Scene Capture 2D can specify a global clip plane, which is useful for portals
	* Requires the global clip plane project setting to be enabled

Change 3226214 on 2016/12/07 by Daniel.Wright

	Improved deferred shadowing with MSAA by upsampling light attenuation intelligently in the base pass
	* If the current fragment's depth doesn't match what was used for deferred shadowing, the neighbor (cross pattern) with the nearest depth's shadowing is used
	* Edge artifacts can still occur where the upsample fails or the shadow factor was computed per-sample due to depth / stencil testing
	* Indirect Occlusion from capsule shadows also uses the nearest depth neighbor UV for no extra cost
	* Base pass on 970 GTX 1.69ms -> 1.85ms (.16ms) in RoboRecall

Change 3226258 on 2016/12/07 by Rolando.Caloca

	Re-saved Infiltrator maps to update reflection captures.
	#jira UE-38759

Change 3227063 on 2016/12/08 by Mark.Satterthwaite

	For Metal platforms ONLY temporarily disable USE_LIGHT_GRID_REFLECTION_CAPTURE_CULLING to avoid UE-37436 while the Nvidia driver team investigate why this doesn't work for them but does for the others. This won't affect non-Metal platforms and the intent is to revert this prior to 4.16 provided we can work through the problem with Nvidia.
	#jira UE-37436

Change 3227120 on 2016/12/08 by Gil.Gribb

	Merging //UE4/Dev-Main@3226895 to Dev-Rendering (//UE4/Dev-Rendering)

Change 3227211 on 2016/12/08 by Arne.Schober

	DR - UE-38585 - Fixing crash where HierInstStaticMesh duplication fails. Also reverting the fix from UE-28189 which is redundant.

Change 3227257 on 2016/12/08 by Marc.Olano

	Extension to PseudoVolumeTexture for more flexible layout
	Change by ryan.brucks

	DR - Fix crash when using custom expressions and using reserved keywords
	#jira UE-39311

Change 3227376 on 2016/12/08 by Mark.Satterthwaite

	Must not include a private header inside the MenuStack public header as that causes compile errors in plugins.

Change 3227415 on 2016/12/08 by Mark.Satterthwaite

	Fix shader compilation due to my disabling of USE_LIGHT_GRID_REFLECTION_CAPTURE_CULLING on Metal - InstancedCompositeTileReflectionCaptureIndices needs to be defined even though Metal doesn't support instanced-stereo rendering.

Change 3227516 on 2016/12/08 by Daniel.Wright

	Implemented UWidgetComponent::GetUsedMaterials

Change 3227521 on 2016/12/08 by Guillaume.Abadie

	Fixes post process volume's indirect lighting color.

	#jira UE-38888

	New upscale filters: Lanczos-2 (new default), Lanczos-3 and Gaussian Unsharp Mask

Change 3227628 on 2016/12/08 by Daniel.Wright

	Removed redundant ResolveSceneDepthTexture from the merge

Change 3227635 on 2016/12/08 by Daniel.Wright

	Forward renderer supports shadowing from movable lights and light functions
	* Only 4 shadow casting movable or stationary lights can overlap at any point in space, otherwise the movable lights will lose their shadows and an on-screen message will be displayed
	* Light functions only work on shadow casting lights since they need a shadowmap channel to be assigned

Change 3227660 on 2016/12/08 by Rolando.Caloca

	DR - vk - Fix r.MobileMSAA on Vulkan
	- r.MobileMSAA is now read-only (to be fixed on 4.16)
	- Show time for PSO creation hitches
	#jira UE-39184

Change 3227704 on 2016/12/08 by Mark.Satterthwaite

	Fix Mac HDR causing incorrect output color encoding being used, HDR support is now entirely off unless you pass -metaledr which will enable it regardless of whether the current display supports HDR (as we haven't written the detection code yet). Fixed the LUT/UI compositing along the way - Mac Metal wasn't using volume LUT as it should have been, RHISupportsVertexShaderLayer now correctly returns false for non-Mac Metal platforms.

Change 3227705 on 2016/12/08 by Daniel.Wright

	Replaced built-in samplers in the nearest depth translucency upsample because the built-in samplers are no longer bound on PC (cl 2852426)

Change 3228940 on 2016/12/09 by Mark.Satterthwaite

	Editor fixes for 4.15:
	- PostProcessTonemap can't fail to bind a texture to the ColorLUT or the subsequent rendering will be garbage: the changes for optimising stereo rendering forgot to account for the Editor's use of Views without States for the asset preview thumbnails. Amended the CombineLUT post-processing to allocate a local output texture when there's no ViewState and read from this when this situation arises which makes everything function again.
	- Don't start render-passes without a valid render-target-array in MetalRHI.

Change 3228950 on 2016/12/09 by Mark.Satterthwaite

	Make GPUSkinCache run on Mac Metal - it wasn't working because it was forcibly disabled on all platforms but for Windows D3D 11.
	- Fixed the Skeleton editor tree trying to access a widget before it has been constructed.
	- Enable GPUSkinCache for Metal SM5: doesn't render correctly, even on AMD, so needs Radar's filing and investigation.

MAJOR FEATURES + CHANGES
==========================

Change 3209340 on 2016/11/23 by Ben.Marsh

	Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.

	Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.

	  * Every header now includes everything it needs to compile.
	        * There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
	        * There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
	  * Every .cpp file includes its matching .h file first.
	        * This helps validate that each header is including everything it needs to compile.
	  * No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
	        * You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
	        * There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
	  * No engine code explicitly includes a precompiled header any more.
	        * We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
	        * PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.

	Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.

Change 3122543 on 2016/09/13 by Ben.Woodhouse

	Override HasOcclusion for Widget3DComponentProxy to detect if the material is has depth testing enabled.

	#jira UE-35878

Change 3122544 on 2016/09/13 by Ben.Woodhouse

	Shadow stencil optimisation with cvar (enabled by default)

	Avoids redundant clearing the stencil buffer for per-object and pre shadows by zeroing the stencil during testing, following discussion on UDN.

	This means we don't benefit from Hi Stencil on GCN for the shadow projection draw calls, but it's still faster in all the cases I could find, including for the player character where the bounding box is quite large. (Note: early stencil still works fine, according to PIX)

	Shadow projection GPU time profiling :
	Test map with 35 characters, stationary directional light
	  - 4ms-2ms on XB1
	  - 2.5ms to 0.9ms on PC (r9-390X)
	  - 3ms-2ms on PS4

	Paragon PS4 (roughly 20% reduced - from ~0.39ms)

Change 3125378 on 2016/09/14 by Arne.Schober

	DR - [UE-34481] - Extract all the State which is necessary to execute the DebugTextDrawingDelegate from the SceneProxy into its own Helpers to be drawn to the canvas later on. The issue was that the SceneProxys are only owned by the RT after their creation and the GT should avoid reading from or writing state to them.

Change 3127130 on 2016/09/15 by Mark.Satterthwaite

	Add overloads to as* functions in hlslcc - HLSL allows you to call these on variables of the same type, in which case it simply returns the existing value but we had only defined the float<->u/int conversions, so hlslcc added implicit casts that broke such cases (i.e. asuint(uint) -> floatBitsToUint(float(uint))). This change defines the missing overloads as returns with regular casts.
	#jira FORT-25869
	#jira UE-34263

Change 3127475 on 2016/09/15 by Rolando.Caloca

	DR - vk - Debug dump

	(Integrated from //UE4/Private-Partner-NREAL/...)

	Alpha output support for postprocess materials (optional via a parameter)

	Needed for end of frame compositing. Could be used to pass intermediate data from one blendable postprocess to another (e.g edge detection)

Change 3128135 on 2016/09/16 by Ben.Woodhouse

	GPU profiler (PS4) - remove bubbles between commandlist submissions from query times

	Use r.ps4.AdjustRenderQueryTimestamps cvar to enable/disable (defaults to on)

	#jira UE-36072

	Improve vector noise tooltips & documentation

Change 3130547 on 2016/09/19 by Ben.Woodhouse

	Fix for ensure fail when initializing point light shadowmaps.

	This came about because cubemap rendertargets always have Extents of (Resolution, 0). The Y component was implicitly used to determine if it was a cubemap, which is odd... The fix was to make the definition explicit via a flag and initialize both the X and Y parameters.

	I suspect the ensure started happening recently due to a more recent change, but fixing the underlying logic seems like the correct fix.
	#jira UE-35837

	#jira UE-29332

Change 3130965 on 2016/09/19 by Arne.Schober

	DR - [UE-35679] - the crash was caused by the Resource of the UTexture being Null. And one of the Kismet Nodes calling a function on that resource. The solution was to disable that call from Kismet when only cooking.

Change 3130967 on 2016/09/19 by Chris.Bunner

	Hid redundant texture sampler properties from texture object parameter.
	Hid redundant texture property input on texture parameter nodes.

	#jira UE-32724

Change 3131118 on 2016/09/19 by Mark.Satterthwaite

	Second attempt - this time with the correct input types. Add overloads to as* functions in hlslcc - HLSL allows you to call these on variables of the same type, in which case it simply returns the existing value but we had only defined the float<->u/int conversions, so hlslcc added implicit casts that broke such cases (i.e. asuint(uint) -> floatBitsToUint(float(uint))).

	DR - Shrink gpu skinning permutations

Change 3131261 on 2016/09/19 by Mark.Satterthwaite

	Fix Metal validation failures due to particle rendering not binding buffers to all buffer inputs declared in the shader.
	ContentExamples Effects no longer aborts complaining that the particle system didn't bind a required buffer.

Change 3131265 on 2016/09/19 by Mark.Satterthwaite

	Fix FMetalDynamicRHI::RHIReadSurfaceData for shared textures on iOS.

Change 3131271 on 2016/09/19 by Mark.Satterthwaite

	Use private memory for the Metal stencil SRV workaround needed on El Capitan.

Change 3131273 on 2016/09/19 by Mark.Satterthwaite

	Disable the lazy-encoder construction in Metal for AMD - there is a situation that causes the lazy construction to perform a clear that isn't wanted and so far this hasn't been tracked down and fixed. Until then, this will render correctly.

Change 3131280 on 2016/09/19 by Mark.Satterthwaite

	For GLSL interpolation mode flags must come before storage mode flags and you can't redeclare the system variable gl_Layer to use a differing interpolation mode.

Change 3131283 on 2016/09/19 by Mark.Satterthwaite

	Change the ShaderCache to not cache resource bindings in the draw states for shader platforms that don't care - reduces the number of draw states considered significantly without reducing effectiveness. We can support ShaderCache with Metal SM5 but not the RHI thread enabled so change when we enable it and make sure we load the binary shader cache.

	DR - vk - Submit Hint
	- Disable framebuffer recycling as its causing a hang

Change 3131625 on 2016/09/19 by Mark.Satterthwaite

	Inside MetalRHI add an optional cache for disposed texture objects so we may reuse them - controlled by CVAR rhi.Metal.TextureCacheMode which must be set prior to running as it can't be changed at runtime. Settings: 0 = off, 1 (default) = will attempt to reuse private memory texture objects within the frame they are released otherwise they are disposed of as before. Setting 2 extends the caching to all textures - though Managed/Shared textures cannot be reused until after the frame in which they were released has been processed on the GPU. In this mode id<MTLTexture> objects are never returned to the OS so in order to conserve VRAM calls to setPurgeableState are made to allow the driver to reclaim unusued memory if required.

Change 3131630 on 2016/09/19 by Mark.Satterthwaite

	More statistics in Metal added to track down where performance was going in a particular project but which may be more generally useful.

	#jira UE-35937

Change 3132696 on 2016/09/20 by Mark.Satterthwaite

	Use set*Bytes to handle uploading buffers < 4Kb when available - this is faster than lots of small Metal buffers and reduces the amount of GPU heap fragmentation. Where the API feature isn't available or hasn't been tested yet we'll use another ring-buffer inside the MetalCommandEncoder to emulate it.

Change 3132772 on 2016/09/20 by Mark.Satterthwaite

	Rework Metal's handling of RHISetStreamSource calls that override the stride of vertex declarations to be much more efficient.

	Duplicate CL #3137164:
	Add stats to track exactly how many command buffers are allocated and committed each frame to work out why Fortnite on AMD is hanging, which turns out to be because each texture update/reallocation ends up in its own command-buffer. This needs to be rethought to pack these into fewer command buffers with the same synchronisation requirements to minimise command-buffer splits but for now we'll just make the default sufficiently large that we shouldn't see the hang until the work is done. Also ensure that command-buffer failure is always fatal - there is no way to recover or continue if a command-buffer fails.

Change 3140360 on 2016/09/26 by Daniel.Wright

	Lighting Scenarios and lightmaps moved to separate package
	* Levels can be marked as lighting scenarios (eg Day, Night).  Lighting is built separately for each lighting scenario with actors / lights in all other scenario levels hidden.  Only one lighting scenario level should be visible at a time in game, and its lightmaps will be applied to the world.
	* Most outputs of the lighting build now go into a separate _BuiltData package.  This improves level Save and AutoSave times as the separate package will only be dirtied after lighting rebuilds.
	* If a lighting scenario is present, all lightmaps are placed inside it's _BuiltData package.  This means that only the currently loaded lighting scenario's lightmaps will be loaded (Day or Night, but not both).  This also means that lightmaps for a streaming level will not be streamed with it.
	* For backwards compatibility, existing lightmaps are moved to a new _BuiltData package on load.
	* Reflection captures and precomputed visibility were not moved to the separate package.  Reflection captures are force updated on load of a lighting scenario level, which can increase load times.

The order of initialisation is different per-platform:

	DR - [UE-33438] - Added a Project Setting to enable Skincache Shader Permuations. The Default value for the Skincache mode was changed to enabled. The reasoning behind this was that it will be auto disabled when Skincache Shaders are disabled, and runtime toggle is a debuging feature that mainly programmers are dealing with. The Recompute Tangents option in the Skinned Mesh is now automatically grayed out when no Skincache Shader Permuations are available.

	The density are computed by the engine but can be overridden by the user in the material tabs.

	Texture streaming intermediate component data is now per material instead of per lod-section.

	New ViewModeParam in FSceneViewFamily allowing context specific param per viewmode.
	This is currently used to show which UV channel and which texture index is being
	shown in the texture streaming accuracy viewmodes.
	This replaces r.Streaming.AnalysisIndex

	Renamed texture streaming viewmodes:
	MeshTexCoordSizeAccuracy -> MeshUVDensityAccuracy
	MaterialTexCoordScalesAccuracy -> MaterialTextureScaleAccuracy
	MaterialTexCoordScalesAnalysis -> OutputMaterialTextureScales

	Improved UV density computation and viewmode.

	DR - Refactoring of the ViewMatrices. Moved the Derived Matrices into the FViewMatrix struct. Made all members private do emphasize the static constness of that struct after creation. Renamed the heavy weight members on this struct to Compute*. Methods that modify The ViewMatrices have been renamed to Hack* to discurage their use in the future until a better solution for those problems is found. The ViewMatrix modification is especially misleading because it only changes the State of the ViewMatrices to read their Position from the Material Editior as if coming from the Lightsource (mainly for manual bilboards) as well as doing someting similar to generate CPU bilboards for shadows.

MAJOR FEATURES + CHANGES

Change 3094167 on 2016/08/18 by Jeff.Fisher

	UEVR-97 Morpheus HMD tracking needs to wait until HMD is fully tracked.
	-Morpheus CALIBRATING/NOT_TRACKED tracking state hmd orientation update disabled and delegates added to present instructions to the user.  This behavior is controlled by morpheus ini setting bDisableHMDOrientationUntilHMDHasBeenTracked, but defaulted to true to avoid subtly bad user experiences.
	#review-3094106 @chad.taylor
	#jira UEVR-97

Change 3104799 on 2016/08/29 by Jeff.Fisher

	UEVR-178 Morpheus HMD Black crescents
	-Switched reprojection frame time for 60/120 mode from 120hz to 60hz so we much better predict where the hmd will be pointing when the frame we are about to render is actually displayed, and are run off the edge of it less often and less severely.  This makes the black crescent artifacts only just visible during very fast head turning.  The kWrapModeMirror change, which will be submitted separately, makes the left and right crescents invisible to me.
	-Renamed the functions for setting the prediction info in the PS4Tracker.
	-Added render frame parameters to sony reprojection functions, these can help with debugging reprojection.
	-Added commented out sce call to get the reprojection debug data.  Not allowed to submit an executable that calls it, but its nice to at least know where one can put it.  May improve this later.
	-Wrapped PS4Tracker->Synchronize call in a check that the tracker handle is valid, because I managed to get it called when it wasn't (probably during hmd power off testing, but I don't remember now).  It should be fine to not do it if the tracker is not functioning.
	#review-3104780 chad.taylor
	#jira UEVR-178

Change 3108423 on 2016/08/31 by Jeff.Fisher

	Morpheus Config Improvements.
	-UEVR-138 Morpheus HMD reprojection wrap mode config setting
	-Can now switch between wrap mode Mirror and ClampToBorder.  Mirror is the default.
	-Made bDisableHMDOrientationUntilHMDHasBeenTracked editable in UE4Editor project settings.
	-Using generic project setting for bStartInVR, removed the morpheus specific one.
	#jira UEVR-138
	#review-3106999 @nick.whiting

Change 3111231 on 2016/09/01 by Jeff.Fisher

	Fixed bStartInVR ini setting.
	-Initial implementation worked via a generic EnableStereo call, which worked, but happened after the hmd setup dialog, which is not what I wanted.
	-Also fixed a tracking frame mismatch assert that hit when I powered the hmd off once, causing it to lose tracking.  Its ok that it doesn't update in that circumstance.
	#review-3111211 @ryan.vance

Change 3115196 on 2016/09/06 by Keli.Hlodversson

	#jira UEVR-128
	Map move controller Select button to Invalid, as it is always handled by the system

Change 3116425 on 2016/09/07 by Chad.Taylor

	PSVR: stereo layers implementation

Change 3116593 on 2016/09/07 by Jeff.Fisher

	UEVR-126 Morpheus HMD connect dialog cancel reactions
	-VR only apps can't allow the player to cancel out of the hmd setup dialog, so lets just pop the dialog up again (sony were ok with a licencee doing this) if an ini setting says to do that.
	-VR/2D apps might want to switch to 2d if the player cancels out of the hmd setup dialog, so there is an ini setting for that.
	-A delegate only implementation is also provided for apps that want to do something else.  This leaves the game rendering in VR mode, and fires the delegate.
	-Refactored to better separate successful HMD acquisition from stereo rendering.  This was necessary to support the delegate only option on startup.  If you start in vr mode with your hmd off and cancel the dialog stereo rendering now starts with default values for the hmd hardware stats (as read from my pvt) instead of crashing trying to use uninitialized data.  When an hmd is connected its values will be read.
	-Refactored to ensure reprojection starts immediately when we call StartReprojection.
	#jira UEVR-126
	#review-3116221

Change 3116754 on 2016/09/07 by Keli.Hlodversson

	bPixelDensityAdaptive is a bool and not a float property

Change 3117692 on 2016/09/08 by Jeff.Fisher

	UEVR-135 Morpheus HMD recent feature error reporting
	UEVR-173 2DVR flexibility (UTexture)
	-Error log for sceHmdReprojectionSetOutputMinColor failure.
	-Made the parameter for 2dVR a UTexture* instead of a UTexture2D*, so it can be a rendertarget, etc.
	-Added error logs for missing texture, invalid texture, wrong texture format to 2DVR.

	#jira UEVR-173
	#review-3116955 @keli.hloedversson

Change 3117990 on 2016/09/08 by Jeff.Fisher

	UEVR-127 Morpheus HMD removal reaction
	-Added VRHeadsetPutOnHead and VRHeadsetRemovedFromHead delegates, and implemented them for Morpheus.
	#jira UEVR-127
	#review-3117968 @keli.hlodversson

Change 3120198 on 2016/09/09 by Jeff.Fisher

	MorpheusReprojector frame complete wait error log
	-Now log a warning if the sceKernalWaitEqueue returns an error.  It not a problem if this happens rarely, but something is very broken if it starts happening continuously.

Change 3121754 on 2016/09/12 by Keli.Hlodversson

	#jira UE-21878 - Also emit VR initialization analytics events in the editor.

Change 3122311 on 2016/09/12 by Nick.Whiting

	Merging fix for Adreno devices rendering black from 4.13.1

Change 3123057 on 2016/09/13 by Keli.Hlodversson

	#jira UE-30097 Use the current value of r.ScreenPercentage on Occulus Rift if it's explicitly set.

	* If the SetBy part of the flags for the console var is SetBy_Constructor, then ignore the value.
	* If it's SetBy_Scalability, then ignore it if it equals 100
	* Else, call SetScreenPercentage using the current value

	The obsolete HMD SCREENPERCENTAGE console command is still available and will override the setting until r.ScreenPercentage is modified the next time.

Change 3123200 on 2016/09/13 by Chad.Taylor

	PS4 Stereo Layer double buffering. Since the overlays are reprojected at 120hz but rendered at 60hz we need to render to a separate buffer than the one being used by reprojection.

Change 3125845 on 2016/09/14 by Keli.Hlodversson

	#jira UE-33996 Add hmd=<name> command line option to allow overriding which HMD module is used.

	Renamed GetModulePriorityKeyName to simply GetModuleKeyName, as this name is now also used to match against the command line options.

Change 3127293 on 2016/09/15 by Jeff.Fisher

	UEVR-225 Morpheus HMD top and bottom black crescents
	-The hidden and visible area meshes for morpheus were too restrictive.  Nudged them out a bit, no black crescents at the top and bottom of the screen.  We are rendering a few more pixels now though.
	#review-3127145 @ryan.vance
	#jira UEVR-225

Change 3130635 on 2016/09/19 by Jeff.Fisher

	UEVR-226 Morpheus HMD mirrored fill wrong on outer edges
	-The setting was never being used, leaving the wrap mode at 0 aka kWrapModeWrap.
	-Refactored how the setting is applied so it works, and is less convoluted.
	#jira UEVR-226
	#review-3129403

Change 3131615 on 2016/09/19 by Keli.Hlodversson

	#jira UE-29341. Update Chaperone bounds when SteamVR tells us they have changed

Change 3136527 on 2016/09/22 by Keli.Hlodversson

	Don't depend on the current state of the VR subsystem when exiting PIE mode to decide whether the main window should be restored. Instead always restore it if it was minimized at the start.

Change 3136652 on 2016/09/22 by Keli.Hlodversson

	Allow shutting down Steam VR subsystem without shutting down the Steam VR plugin completely in response to quitting from the SteamVR overlay. Enabling stereo rendering again will reinitialize SteamVR. This is useful when using PIE in VR mode as it allows entereing it again without restarting the editor. Also fixes crashes by first disabinge stereo rendering a short while before shutting down the VR subsystem.

	#jira UE-35940

Change 3138901 on 2016/09/23 by Ryan.Vance

	Merging 3138521 using OdinToDevVR to bring over temporary forward lighting ISR changes for 4.14

Change 3141614 on 2016/09/27 by Keli.Hlodversson

	Implement GetNumOfTrackingSensors and GetTrackingSensorProperties on SteamVR.

	#jira UE-32994

Change 3141948 on 2016/09/27 by Jeff.Fisher

	UEVR-242 Is AddControllerYawInput not allowed when morpheus is enabled?
	-Indeed it did not work.  Looks like morpheus would not accumulate the yaw, so it would be reset every frame.  I made the implementation of ApplyHmdRotation very similar to the one used for occulus (also similar to other platforms) to fix this.
	#jira UEVR-242
	#review-3141933 keli.hlodversson

	Merging latest drop from OSVR

Change 3144221 on 2016/09/28 by Keli.Hlodversson

	Implement GetTrackingSensorProperties on PS4
	#jira UE-32994

Change 3144352 on 2016/09/28 by Ryan.Vance

	Initial implementation of mobile multi-view.
	This is non-functioning and requires a lot more work, but enough of the framework exists to make the 4.14 branch for an experimental release.

Change 3144585 on 2016/09/29 by Jeff.Fisher

	UEVR-14 PSVR Support for 90Hz to 90Hz, and 120Hz to 120Hz
	-Enum setting added for the three frame sequences.
	-90Hz mode is trying to run camera updates at 90hz, but they can only run at 60 so every third one fails.  This works, but its dubious.
	-Feature marked as experimental for now because of that 90hz tracking issue, and the lack of testing.
	-Defaulting to 60/120.
	#jira UEVR-14
	#review-3143486 chad.taylor nick.whiting

Change 3145263 on 2016/09/29 by Nick.Whiting

	Fix for constructor initialization order in StereoLayerComponent, which threw a warning on Clang

Change 3145536 on 2016/09/29 by Nick.Whiting

	Fixes for project files to prevent mystery pop up from CAPI

Change 3145663 on 2016/09/29 by Keli.Hlodversson

	PSVR: Make sure the camera orientation returned from GetTrackingSensorProperties points in the right direction.

Change 3145670 on 2016/09/29 by Keli.Hlodversson

	For some reason the orientation of the Oculus tracking sensor is reported as pointing backwards. This flips it around to face front

MAJOR FEATURES + CHANGES
==========================

Change 3091951 on 2016/08/17 by Chris.Bunner

	(Duplicate) CL 3090919: Fixed edge case interactions in HLOD ray rejection logic in Lightmass.

Change 3093162 on 2016/08/18 by Ben.Woodhouse

	Fix minor memory leak (missing delete of RT Heartbeat thread)

Change 3093470 on 2016/08/18 by Ben.Woodhouse

	Fix minor leak in FMonitoredProcess - the Thread member would get leaked if the FMonitoredProcess was cancelled, because it gets NULLed without deleting it.  Fix is to add a bool to keep track of whether the thread is running, rather than using the Thread pointer.
	Also fixes a race condition where the FMonitoredProcess::Thread member could get initialized after the thread had completed. This would cause IsRunning to never return false, even if the thread has completed, and the editor would hang on startup (this was fixed by setting bIsRunning to true before creating the thread)

Change 3093698 on 2016/08/18 by Daniel.Wright

	Translucent lighting volume draw event cleanup

Change 3093700 on 2016/08/18 by Daniel.Wright

	Merging stereo planar reflections from Odin.

Change 3094060 on 2016/08/18 by Daniel.Wright

	Fully featured base pass reflection captures with blending and parallax correction
	* Used in the forward renderer when materials opt-in to 'High Quality Reflections'
	* Used in the deferred renderer for translucent 'Surface ForwardShading' materials
	* Reflection captures are culled to a frustum space grid using the same reverse linked-list method as lights in the forward renderer
	* Fixed grid culling in stereo / splitscreen
	* The ReflectionEnvironment compute shader used in the deferred path also uses the culled grid now which reduces its cost from .93ms -> .70ms on 970 GTX.  PS4 cost is about the same.
	* Capsule indirect self-shadowing is now reduced in the forward path to match deferred, and both are controlled by r.CapsuleIndirectShadowSelfShadowIntensity
	* SetupHZB is now skipped when SSAO / SSR / HZB are all disabled

Change 3094160 on 2016/08/18 by Daniel.Wright

	CIS fixes

Change 3094899 on 2016/08/19 by Ben.Woodhouse

Change 3098418 on 2016/08/23 by Olaf.Piesche

	Moving vertex factory dirtying to always happen in-editor for mesh emitters on dynamic data reinitialization; there are several cases in which this needs to happen (some material changes, mesh reimports...) which are difficult to track, so in-editor we just always recreate the mesh particle vertex factory with the dynamic data.

	#jira UE-34838

Change 3098556 on 2016/08/23 by Daniel.Wright

	Lightmass area shadows only mark texels as mapped inside the light's influence, which fixes multiple stationary lights with bUseAreaShadowsForStationaryLight interfering.

	DR - vk - Fixed crash when using vertex shaders with no descriptors

Change 3099173 on 2016/08/24 by Ben.Woodhouse

	Fixed various issues with subsurface profile, for checkerboard and non-checkerboard code paths

	- Re-enable non-checkerboard skin by default

	- Checkerboard issues fixed:
	    - Emissive lighting was being applied twice due to not taking checkerboard pattern into account
	    - Emissive lighting was modulated by basecolor in the recombine
	    - Metallic materials were contributing specular lighting to the diffuse channel

	 - Non-checkerboard fixes:
	    - Fix write mask during SkyLightDiffuse so alpha is updated correctly
	    - Metallic specular lighting was broken (specularColor was lerping to white instead of baseColor)

	 - Optimisation: Fall back to default lit for pixels where the opacity is 0.
	    - For non-checkerboard, this gives better handling of metallic/emissive for pixels where SSS is not required (non-CB RGBA encoding for diffuse/spec doesn't cope well with colored specular or emissive)
	    - For checkerboard, this gives similar results in terms of shading, but we get full-resolution shading on non SSS pixels

	FloatRGB  is now always supported.

	If 11:11:10 isn't supported by hardware this format by definition will map to a different format meaning it is always supported.

Change 3099987 on 2016/08/24 by Daniel.Wright

	* Always creating the local light buffer, even if it won't be used by the shader
	* Transition ViewState FRWBuffers to writable at the beginning of a new frame

==========================
MAJOR FEATURES + CHANGES
==========================

Change 3028958 on 2016/06/27 by Ben.Woodhouse

	Fix for perf issue with GetSingleFinalDataConst

	This was caused by the LPV integration/switch to blendables. Now we cache the flag for the directionalocclusion in the LPV class. This reduces calls to GetSingleFinalDataConst on the blendable data (potentially slow), and makes things a bit cleaner and consistent.

	Tested in QAGame editor (with LPV enabled in ConsoleSettings.ini)

	#jira UE-26179

Change 3029401 on 2016/06/27 by Rolando.Caloca

	DR - More vk logging

Change 3029549 on 2016/06/27 by Uriel.Doyon

	Refactored "r.OnlyStreamInTextures" into "r.Streaming.FullyLoadUsedTextures", making it fully load every used textures, as an alternative to disabling texture streaming.
	New options "r.Streaming.UsePerTextureBias" that assign a  bias between 0 and MipBias to each texture in order to fit in budget.
	Fixed crash when disabling texture streaming.
	Fixed issue when disabling texture streaming that would make current loaded texture low res.
	New logic to prevent retrying to cancel a streaming request more than once.
	Pending load request of one extra mip will not be cancelled anymore.
	Changed UTexture2D from float to double. Also using FApp::GetCurrentTime() instead of FPlatformTime::Seconds().
	#jira UE-32197
	#jira UE-31102

Change 3029837 on 2016/06/27 by David.Hill

	Fixed Shutter SM4 not working when using compute shader eye-adaptation
	#jira UE-32443

	The default eye adaptation value was missing.

Change 3030039 on 2016/06/27 by Uriel.Doyon

	Fix for crash when landscape materials are used in the Texture Streaming Build.
	#jira UE-32196

Change 3030081 on 2016/06/27 by Uriel.Doyon

	Updated MaterialTexCoordScalesPixelShader to use PackedEyeIndex, preventing crash when building the map with stereo rendering enabled.

Change 3030401 on 2016/06/28 by Ben.Woodhouse

	Perf Monitor: Fix for perf warning due to cvar FindConsoleVariable being called too frequently. Tested in QAGame editor (DX11)
	#jira UE-31238

Change 3030607 on 2016/06/28 by Marc.Olano

	Random Number generators: fixed bug in TEA, added integer and float Blum-Blum-Shub. BBS is way cheaper for similar quality, suggest it for future use.

Change 3030627 on 2016/06/28 by Ben.Woodhouse

	Fix for warning. CVar naming scope clash (doesn't appear to happen in vs2015).

Change 3030809 on 2016/06/28 by Marc.Olano

	Noise shader function rename & perf improvement.

	Due to incorrect terminology in internet soruces, previous "Perlin" noise was not, in fact, Perlin noise. Now more accurately called "Value" noise. 6x perf improvement for value noise by changing random number function to BBS. Also updated instruction counts in UI tooltips.

Change 3030850 on 2016/06/28 by Marc.Olano

	Rename & redirect noise material enums. At some point these got switched around and no longer accurately described the noise options the selected. Redirect, so all existing content will continue to work as-is. Updated UDN docs to match.

Change 3030981 on 2016/06/28 by Rolando.Caloca

	DR - vk - More logging

Change 3031056 on 2016/06/28 by Marc.Olano

Change 3035577 on 2016/07/01 by Marc.Olano

	Tiling noise. Adds tiling option for gradient, gradient texture, and value noise in the noise material node. Tiling is more expensive, but allows noise functions to be baked into a seamless repeating texture.

Change 3035587 on 2016/07/01 by Ben.Woodhouse

	Fix for async SSAO bug (SSAO Async Compute results are used before the async job wait)

	#jira UE-32709

Change 3035618 on 2016/07/01 by Olaf.Piesche

	Alpha Coverage Preservation
	-Textures have a Alpha Preservation Vec4 property which dictates about much of that channel to preserve down the mip chain during mip generation.
	#Jira UE-31986

Change 3036041 on 2016/07/01 by Rolando.Caloca

	DR - vk - Fix for 32bit

Change 3036433 on 2016/07/01 by Rolando.Caloca

	DR - More vk logging

Change 3036935 on 2016/07/04 by Simon.Tovey

	Removing Data Objects

Change 3036942 on 2016/07/04 by Ben.Woodhouse

	Fix for decal rendering resource leak

	The cause was that FD3D11BoundRenderTargets doesn't support setting RTs sparsely. So if one element is NULL, it won't release the ones after it.

	The sparse RT layout happened as a result of a change back in October, which meant that GBuffers for decals could be set sparsely, dependent on whether the decal wrote to the normalbuffer

	This change adds support for sparsely bound rendertargets in FD3D11BoundRenderTargets.

	#jira UE-32602

Change 3037563 on 2016/07/05 by Chris.Bunner

	HLOD self-shadowing in baked lighting fix.

	#jira UE-22627

Change 3038209 on 2016/07/05 by Rolando.Caloca

	DR - vk - Android compile fix

Change 3038644 on 2016/07/05 by Uriel.Doyon

	Added LerpRange that allows to lerp between two rotators without taking the sortest path.

Change 3038820 on 2016/07/05 by Uriel.Doyon

	Selecting streaming accuracy view modes will not automatically generate missing visualization data.

Change 3039332 on 2016/07/06 by John.Billon

	-Made MaxGPUSkinBonesCvar a FAutoConsoleVariableRef and moved it to mesh utilitles from console manager to fix a thread initialization problem.
	#Jira UE-31710

Change 3039454 on 2016/07/06 by Simon.Tovey

	Moved all Niagara files from Engine and UnrealEd to remove dependancies and increase compile times.
	Niagara is now 99.999% decoupled from engine and editor so development should be much streamlined.

	Plus a few other edits to remove Curves/DataObjects that I missed in last CL.

Change 3039517 on 2016/07/06 by Gil.Gribb

	Merging //UE4/Dev-Main@3039013 to Dev-Rendering (//UE4/Dev-Rendering)

Change 3039587 on 2016/07/06 by Rolando.Caloca

	DR - vk logging, submit counter

	DR - Allow more samplers on GL4
	#jira UE-32628
	#jira UE-32744

Change 3039661 on 2016/07/06 by Daniel.Wright

	Fixed non-directional DFAO occlusion on specular 'r.AOSpecularOcclusionMode 0'
	Skylight occlusion tint now applies to specular
	Skylight occlusion tint on diffuse is now correctly affected by DiffuseColor

Change 3039960 on 2016/07/06 by Daniel.Wright

	Forward renderer initial implementation
	* Point and spot lights are culled to a frustum space grid, base pass loops over culled lights.
	* Light culling uses a reverse linked list to avoid a per-cell limit, and the linked list is compacted to an array before the base pass.
	* New cvars to control light culling: r.Forward.MaxCulledLightsPerCell, r.Forward.LightGridSizeZ, r.Forward.LightGridPixelSize
	* A full Z Prepass is forced with forward shading.  This allows deferred rendering before the base pass of shadow projection methods that only rely on depth.
	* Dynamic shadows are packed based on the assigned stationary light ShadowMapChannel, since stationary lights are already restricted to 4 overlapping.
	* GBuffer render targets are still allocated
	* Fixed several issues in parallax corrected base pass reflections - not blending out box shape, discontinuity in reflection vector, not blending with stationary skylight properly
	* Forward shading is now used for TLM_SurfacePerPixelLighting translucency in the deferred path
	* Notable missing features: shadowing of translucency, support for various translucency lighting modes, multiple blended reflection captures

Change 3040050 on 2016/07/06 by Daniel.Wright

	Added r.Shadow.WholeSceneShadowCacheMb, which defaults to 150, to limit how much memory can be spent caching whole scene shadowmaps

Change 3040160 on 2016/07/06 by Daniel.Wright

	Fixed tile artifacts in indirect capsule shadows from doing the scaled sphere vs tile bounding sphere intersection in the wrong space

Change 3040163 on 2016/07/06 by Rolando.Caloca

	DR - vk - More logging

Change 3040257 on 2016/07/06 by Daniel.Wright

	Skylights aren't captured until their level is made visible- fixes the case where skylights capture too early

Change 3040316 on 2016/07/06 by Daniel.Wright

	PerObject shadows from point / spot lights do the light source pull back based on subject box size, not subject radius, since the box is used to find a valid < 90 degree projection.  Fix from licensee

Change 3040361 on 2016/07/06 by Daniel.Wright

	Fixed TexCreate_UAV being used on translucency volume textures in SM4

Change 3040402 on 2016/07/06 by Rolando.Caloca
